Filed: 1940-05-01
Abstract: 540,892. Filing papers. SMITH, & SON, Ltd., W. H., WISDOM, H. A., and LOTZ, H. G. DE. May 1, 1940, No. 7866. [Class 146 (i)] Loose leaves, &c. are secured in a binder by a single flexible element extending through holes in the covers and holes or notches in the leaves, the element being sufficiently loose to permit release of the units and then being stretched and passed over a stud 21 near the free edge of back cover 6 when the leaves are to be retained. The element consists of an elastic cord 9 with transverse end tags 15 passed through eyeletted holes 13, 14, 16 .. 19 in the covers 5, 6 and through notches 11 in the leaves. Element may consist of an inextensible cord and the stud be replaced by a spring-urged hook. Specifications 277,788 and 337,854, [both in Class 46 (i)], are referred to.

Title: Improvements in tunnel kilns
IPC: F27B9/08
Filed: 1934-03-13
Abstract: 414,610. Tunnel kilns. SHOOK, T. W., Kingsway Chambers, Kingsway, Stoke-on- Trent. March 13, 1934, No. 7878. [Class 51 (ii).] In a tunnel kiln having side combustion chambers 14 shut off from the ware tunnel by heat-radiating plates 8, cold air is supplied under controlled pressure by a fan 40 to the cooling zone 12, and, after being heated by contact with the outgoing goods, is circulated through the ware in the heating zone 11 and finally passed to the combustion chambers 14 to support combustion therein. As shown in Fig. 2, the air passes downwardly through apertures 36 in the ware-supporting platforms 22 to flues 35 in the trucks 15 and from thence to spaced passages 29 and to side flues 32. The main burners 18 induce secondary air, in quantities controlled by dampers 30, 31, from both the passages 29 and the flues 32, while the latter also supply secondary air, through passages 33 controlled by dampers 34, to auxiliary burners 20 which deliver directly on to muffle blocks 21 having an inclined face to radiate heat on to the undersides of the platforms 22. Primary air is supplied to the burners 18, 20, by a fan 39, Fig. 1<a>, which is in communication with the side air flues 32. The burners 18, 20 are staggered on opposite sides of the tunnel, and relief ports 5 are provided to permit the escape of a portion of the circulating air ; this escaping air may be led to the fan 39 or used for drying or other purposes. The waste gases pass along the combustion chambers 14 to exhaust flues 47 at the inlet end of the kiln, these flues being connected to an exhausting fan 17 and also communicating, through damper-controlled openings 46, with the tunnel so as to provide for the withdrawal of water vapour &c. given off in the preheating zone 10. Dampers 19 are arranged between the ends of the combustion chambers 14 and the exhaust flues 47. The fan 40 also supplies air through a branch 43 to a flue extending over the roof of the cooling zone 12, the air thus heated being supplied through an external pipe to slots in the crown of the preheating zone 10. Rubbing seals, formed by insets 24, 25 of insulating material, are provided between the platforms 22 and the muffle blocks 21 and between the bodies of the trucks 15 and the lower side walls of the tunnel ; the trucks also carry sealing plates 48 co-operating with sand troughs 49.

IPC: B08B9/36
Filed: 1918-05-10
Abstract: 125,520. Rude, J. M. May 10, 1918. Cans and like receptacles, cleansing. - Apparatus for brushing the interiors of cans &c. comprises segmental brush elements 16 which are expanded by being moved laterally on the coned supports 12 against the action of springs 24. The can is placed over the brushes by hand and the bottom bears against a rubber ring 26 to take up the end thrust of the springs and prevent undue wear of the end bristles. Each segment of the brush is guided on the corresponding support 12 by an undercut groove and tongue connexion, and the extent of the movement is limited by a projecting screw 21. Water is admitted by an axial pipe 6 inside the rotary driving sleeve 3, and escapes through the radial spaces 15. The coned supports are connected at their outer ends by a plate 13, and are secured to a rotary screwed cap 9 at their inner ends.

[Also in Division G2] A cine projector camera, or tape recorder has an endless coil of film supported on annular disc 1 rotatable about a vertical axis through a central stationary disc 2 having peripheral idle rollers 3 which define the inner film winding. Disc 1 is driven in direction A and may have a system of pairs of rollers (5), as in Fig. 2 (not shown), rotatable about radial axes, the film leaving the inner convolution and returning to the outer. Film may pass horizontally or vertically through the projection gate. A plurality of film carrying discs 1 may be used for long lengths of endless film. In the case of a tape recorder, disc 1 is covered by annular frame (24), Figs. 9-15 (not shown), to which is detachably fastened a cover plate (21) with dependent idle rollers (3) engaging the film. Slots (23) and (29) allow exit and return of the film from the cassette so formed. In use, disc (21) is released and raised and seated by projections (22) on portions (27) of frame (24), Fig. 13, whereby disc (1) may rotate freely as the idle roller shafts are lifted from the recesses (30) in the disc. For multiple-track tapes electrically conductive marks for each track are detected by contactor rollers (45, 46, 47), Fig. 16 (not shown), whereby an electrical signal is used to rotate a cam disc which tilts the magnetic head (43) to scan the next track. The last mark may actuate re-wind mechanism.

Title: Improvements in or relating to friction clutches

Filed: 1951-04-09
Abstract: 707,998. Controlling friction clutches. BRITISH INSULATED CALLENDER'S CABLES, Ltd. April 8, 1952 [April 9, 1951], No. 8204/51. Class 80 (2) A friction clutch has the pressure between the frictionally co-operable surfaces of its two axially aligned members controlled by means of fluid pressure acting on a flexible diaphragm, which forms part of a stationary diaphragm chamber, located outside and coaxial with the clutch members, the flexible diaphragm being mechanically coupled to one of the said clutch members. As shown, a driving clutch member 4 is keyed to a shaft 1 carrying rotatably a driven clutch member 10, the clutch engaging force being controlled by the admission of pressure fluid to a stationary diaphragm chamber 19. The central part of the diaphragm 21, of rubber &c., is connected to a stem 26 secured to a thrust plate 28 which carries two bolts 29 one on each side of a supporting bearing 2 for the clutch shaft, connected in turn to a thrust race 18 which transmits movement of the diaphragm in both directions to the axially movable clutch member 4. The stem 26 is surrounded by a compression spring 30, between a plate clamping the centre of the diaphragm and a nut 27 adjustable on the shaft supporting means, the spring serving to disengage the clutch and move the driving member 4 axially an extent determined by an adjustable stop 32. Compressed air or other fluid is admitted to the diaphragm chamber through a passage 34, and a drain cook 36 is provided. As shown, the centre of the diaphragm moves axially under the influence of the working fluid pressure, but as a modification the centre of the diaphragm may be fixed and the outer part coupled to the axially movable clutch member. The clutch is described as being suitable for use in take-up machines for electrical cables, associated with continuous vulcanizing machines, in which the speed of rotation of the take-up reed is controlled automatically, to coincide with the speed of the cable being produced, by a jockey pulley engaging the cable and acting, on variation of the cable tension on completion of each additional layer of cable wound on the reel, to move the pressure fluid control valve so as to vary the slip of the clutch and hence change the angular velocity of the reel. Specification 707,999 is referred to.
